photo correction: colour/white balance question.

you know how most applications allow white balance/colour correction through a temperature/kelvin slider which seems to alter the colour along one plane of the colour circle, what is the function called that alters the colour in a different plane?

I've tried using the individual component values but it's a bit like setting suspension rebound/compression settings - I seem to do more harm than good, simple functions seem to work for me best, quicker as well.

10 basic tips

1. Hold It Steady

A problem with many photographs is that they're blurry. Avoid 'camera shake' by holding the camera steady. Use both hands, resting your elbows on your chest, or use a wall for support. Relax: don't tense up. You're a marksman/woman holding a gun and it must be steady to shoot.

2. Put The Sun Behind You

A photograph is all about light so always think of how the light is striking your subject. The best bet is to move around so that the sun is behind you and to one side. This front lighting brings out color and shades, and the slight angle (side lighting) produces some shadow to indicate texture and form.

3. Get Closer

The best shots are simple so move closer and remove any clutter from the picture. If you look at most 'people' shots they don¹t show the whole body so you don't need to either. Move close, fill the frame with just the face, or even overflow it. Give your shot some impact. Use a zoom to crop the image tighter.

4. Choose A Format

Which way you hold the camera affects what is emphasized in your shot. For tall things (Redwoods, Half Dome) a vertical format emphasize height. Use a horizontal format to show the dramatic sweep of the mountains.

5. Include People

Photographs solely of landscape and rocks are enjoyable to take but often dull to look at. Include some of your friends, companions, family, or even people passing by, to add human interest. If there's no one around, include yourself with the self-timer.

Have you ever got your photos back only to discover that something that looked awe-inspiring at the time looks dull on paper? This is because your eye needs some reference point to judge scale. Add a person, car, or something of known size to indicate the magnitude of the scenery.

6. Consider Variety

You may take the greatest shots but if they're all the same type or style, they may be dull to look at. Spice up your collection by adding variety. Include landscapes and people shots, close ups and wide angles, good weather and bad weather. Take personal shots that remember the 'being there' - friends that you meet, your hotel/campsite, transportation, street or hiking signposts.

7. Add Depth

Depth is an important quality of good photographs. We want the viewer to think that they're not looking at a flat picture, but through a window, into a three-dimensional world. Add pointers to assist the eye. If your subject is a distant mountain, add a person or a tree in the foreground. A wide angle lens can exaggerate this perspective.

8. Use Proportion

The beauty of an image is often in its proportions. A popular technique with artists is called the Rule of Thirds. Imagine the frame divided into thirds, both horizontally and vertically, like a Tic-Tac-Toe board. Now place your subject on one of the lines or intersections. Always centering your subject can get dull. Use the Rule of Thirds to add variety and interest.

9. Search For Details

It's always tempting to use a wide angle lens and 'get everything in'. However, this can be too much and you may loose the impact. Instead, zoom in with a longer lens and find some representative detail. A shot of an entire sequoia tree just looks like a tree. But a shot of just the tree's wide base, with a person for scale, is more powerful.

10. Position The Horizon

Where you place the horizon in your shot affects what is emphasized. To show the land, use a high horizon. To show the sky, use a low horizon. Be creative.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
